Your VW loses power under load and blows black smoke? Likely EGR/DPF issues. Here’s what to check first and if it’s safe to drive.
First, a quick note about the Volkswagen ID.4
I want to start with a friendly heads-up: the Volkswagen ID.4 is a fully electric SUV, so it doesn't have a diesel engine, an EGR valve, or a DPF. If you're experiencing these symptoms, you might be driving a different VW diesel model (like a Golf TDI, Passat TDI, or Tiguan TDI) — or perhaps you're asking for a friend. Either way, I'll cover the classic diesel issue you're describing, because the advice applies to any modern VW with a TDI engine.
